The Series II power conditioners feature Furman's revolutionary Series MultiStage Protection Plus (SMP+) circuit, as well as our exclusive Linear Filtering Technology (LiFT). Together, these technologies comprise what is, without question, the world's most advanced and comprehensive transient voltage surge suppressor / conditioner. trusted over-voltage circuitry protects against all too frequent accidental connections to 208 or 240 VAC, by shutting off the incoming power until the over voltage condition is corrected. [For E versions: Furman's SMP+ clamps at 376 VpK, (266 VAC RMS.)] LiFT (Linear Filtering Technology) Unfortunately, traditional AC filter - conditioners have been designed for unrealistic laboratory conditions. Prior technologies, whether multiple pole filter or conventional series mode, could actually harm audio and video performance more than they help, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs can actually add more than 10 dB of noise to the incoming AC line! Worse still, lost digital data, the need to re-boot digital pre-sets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman's SMP+ with LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground. SMP+ (Series Multi-Stage Protection Plus) Furman's SMP+ surge suppression virtually eliminates service calls. Traditional surge suppression circuits "sacrifice" themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system, and repair of your surge suppressor. Not so with SMP+. With Furman's SMP+, damaging transient voltages are safely absorbed, clamped, and dissipated. Unique to Furman's SMP+ is its unparalleled clamping voltage. While other designs offer clamping voltages that are well above 330 Vpk, Furman's SMP+ clamps at 188 Vpk, (133 VAC RMS). This unprecedented level of protection is only available with Furman's SMP+ technology.

ADDITIONAL F E A T U R E S PL-PRO SERIES II The PL-PRO II features LED rack lights which produce virtually no heat and provide an extremely long life span. A dimmer control for the rack lights allows the user to adjust the level of illumination or simply switch the lights off. A rear mounted BNC jack accepts any standard (12VAC 0.5 amp) gooseneck lamp for rear rack illumination. Additionally, the PL-PRO II offers a 20 segment LED bar-graph meter that displays incoming voltage between 90 and 128 volts in 2-volt steps. The normal range voltages are indicated in green, with moderately and extremely high or low voltages in yellow and red respectively. The voltmeter's accuracy is ±2 volts. It can easily be re-calibrated, if necessary.(Eversions 180 ­ 256 VAC in 4 volt steps) The PL-PRO D II features LED rack lights which produce virtually no heat and provide an extremely long life span. A dimmer control for the rack lights allows the user to adjust the level of illumination. A rear mounted BNC jack accepts any standard (12VAC 0.5 amp) gooseneck lamp for rear rack illumination. Additionally, the PL-PRO D II offers a laboratory precision digital meter that displays incoming voltage in 1-volt steps. The voltmeter's accuracy is ±1.5 volt. The PL-PRO D II has a master magnetic circuit breaker switch for the front and rear outlets that is protected from accidental disconnection by a hinged cover. The PL-PRO D II also features a 10 foot, 12 gauge heavy-duty power cable. PM-PRO SERIES II The PM-PRO II features two laboratory precision digital meters that display both incoming voltage in 1-volt steps, and a true R.M.S. current meter that measures the AC power draw within 0.5 amp. A rear mounted BNC jack accepts any standard (12VAC 0.5 amp) gooseneck lamp for rear rack illumination. The PM-PRO II has a master magnetic circuit breaker switch for the front and rear outlets that is protected from accidental disconnection by a hinged cover. The PM-PRO II also features a 10 foot, 12 gauge heavy-duty power cable. The PL-PRO II has a master magnetic circuit breaker switch for the front and rear outlets that is protected from accidental disconnection by a hinged cover. The PL-PRO II also features a 10 foot, 12 gauge heavy-duty power cable. PL-PRO D SERIES II 4 SERIES II 20 amp powER CondItIonERS O P E R AT I O N Retractable Rack Lights, Rear panel Lamp and dimmer Control: The PL-PRO II and PL-PRO D II utilize a dimmer control for the two retractable front panel light tubes. The dimmer knob controls the brightness of both light fixtures. Turn it clockwise to increase brightness; turn it counterclockwise to decrease brightness. When the lights are not in use, we recommend turning the dimmer fully counterclockwise to maximize the life of the LED's, however, this is not absolutely necessary. Whether the light tubes are retracted or flush with the front panel, there will be no appreciable heat regardless of dimmer setting due to the efficiency of our full light spectrum LED's. All Series II units feature a rear rack BNC socket which will accept any 12 VAC (0.5A) gooseneck lamp assembly, (such as the Furman GN-LED or GN-I). Simply slide the BNC plug over the socket and rotate clockwise until the connector snaps into the locked position. The rear rack lamp can be powered on or off with the rear light power switch located on the far left of the front panel. The Series II's front panel LED lamps must be replaced by qualified Furman service personnel. multi-Segment LEd voltmeter: (pL-pRo II only) This three-color, 20-LED bargraph is an accurate, self checking AC voltmeter that continually measures normal voltages. The meter reads from 90 to 128 volts in 2 volt increments (PL-PRO E II: 180 to 256 volts, in 4 volt increments). The normal range voltages are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively. The voltmeter provides three special flashing patterns to indicate abnormal conditions.

(2) If all of the LED's on the voltmeter flash, the input voltage is marginally high. Power to the PL-PRO's outlets will remain unless the incoming voltage rises above the Extreme Voltage Shutdown cutoff voltage (135 - 140 volts / 260 ­ 265 volts E version / 120 ­ 125 volts J version). (3) If none of the LED's on the voltmeter are lit, and the Extreme Voltages LED indicator is illuminated, then the PLPlus II has shut down power to its outlets because the input voltage is in a range considered extreme (in excess of 135 volts - 260 volts E version / 120 volts J version). digital Voltmeter: (pL-pRo d II and pm-pRo II only) Furman's laboratory precision AC digital voltmeter continually measures incoming voltages, within a typical tolerance of +/1.5VAC. It should be noted that the voltage reading is incoming. No adjustment should be necessary on these units. digital Current meter: (pm-pRo II only) Furman's laboratory precision AC digital current meter continually measures the total circuit AC load, within a typical tolerance of +/0.5 amp. Because these meters feature true R.M.S. technology, the current readings are accurate regardless of load conditions (capacitive, inductive or resistive). notE: The PL-PRO II, PL-PRO D II, and PMPRO D II, do not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you may benefit from the use of one of Furman's AC Line Voltage Regulators. on/off Circuit Breaker: This 20 amp capacity magnetic circuit breaker switch is specifically designed to stand up to the enormous high inrush current demands of many Power Amplifiers. Additionally, the switch is shielded from accidental power disconnection with a hinged cover. (E-versions feature 16 amp capacity) Extreme Voltage Shutdown Indicator: This LED is normally off. It monitors a hazard common in the entertainment industry: wiring faults ­ for example, accidental connection to 220VAC where 120VAC is expected, or an open neutral from a 208 or 240VAC feed.
